Homework 6 The period of a pendulum, T, is assumed (correctly or incorrectly) to depend on its mass, M, the length of the pendulum. P, the acceleration due to gravity, 9, and the angle of swing, O. Using dimensional analysis, nondimensionalize the period, T, and express its dependence on the other non-dimensional terms. Under certain […]
If the mass of the bullet is m=27g, the mass of the pendulum is M=0.61kg, and the height they rise to after the bullet strikes the mass is h=20cm. Calculate the initial speed of the bullet, v (in m/s).
Two physics home work problems A ballistic pendulum is used to measure the speed of a fast-moving objects such as bullets. If a bullet is fired into a large block suspended by some light wires. The bullet is stopped by the block, and the entire system swings up to a height h. If the mass […]
Explain how you can graphically determine g of Earth using Period2 vs. Length graph? Obtain the value of g by doing a curve fitting and compare it with the known value of 9.81 m/s2.
Time Period of a Simple Pendulum Link for online lab: https://phet.colorado.edu/en/simulation/pendulum-lab OBJECTIVES: Investigate the factors affecting time period of a simple pendulum. Determine gravitational field strength at a location by swinging a simple pendulum and performing curve fitting on linearized data. PROCEDURE: Click on the Intro window. Click on Stopwatch. Make sure that speed is […]
